f. The presentA invention relates to a handling device. i

,-.Animportant object of the invention is to provide a handling device, and particularly a. device adapted for the handling of sheet glass. l V

Another object of the invention is to provide a sheet glass lifting. device including clamping members and a handle, the clamping members being made operative and inoperative by manipulation of the handle.

Another object of the invention is to provide a device of this charactei` comprising fa body portion having glass clamping plates pivotally associated therewith, and a handle for `moving the glass clamping plates into an operative position when it is desired to handle la sheet of glass. A further obj ect of the invention is to pro- 0 vide a. device of this character comprising a body portion having glass clamping plates pivotally associated therewith, and a handle 'having a cam member adapted for enga inent with a portion of said plates, where y upon movement of the handle in Vone direction the plates will be moved into an operative position, and means for normally urging said ,plates into an'inoperative position, so that when the handle is moved in the opposite directionthe device can easily be removed from :the sheet. v

A still further object of the invention is to Aprovide a handling device of this jcharacter comprising a body portion, glass clamping plates 'pivotally vassociated therewith, and a pivoted handle member having means carried thereby for placing theclamping plates in that is exerted upwardly on said handle the tighter the clamps will engage the sheet of glass, said sheet being released upon down- ,ward vertical movement of said handle.

Other objects and advantages of the invention will become more apparent during the course of the following description when .taken in connection with the accompanying drawings. v y

l In the drawings wherein like numerals are employed to designate like parts throughout the same, l y

Fig. 1 is a top plan view of the lifting or lhandling device in operation, and partly in section for the purpose of illustration,

Fig. 2 is a side elevation of the device in use, and

Fig` 3 is an end view thereof.

The present invention has been designed primarily to facilitate the handling of sheet glass, `and is particularly well" adapted for the handling of relatively large sheets. :Of course the invention is not in any way limited ,to the handling of large lsheets of glass. The lifting device comprises a body portion5 having a groove or recess 6 formed therein which is preferably lined or covered with rubber, felt, or the like 7. Pivotally associated with the body portion 5 are glass clamping plates 8 and 9. Theplates comprise the members 10 adapted forcontact with the glass sheet 11, and to prevent injury to the glass and to ob-V tain the proper friction to permit handling of said sheet, the membersf l() may be provided `with la suitable covering 12. 'The arm portions 13 of .the plate members are pivotally connected to thebody portion by means of the pins 14 extending through the sleeves'l on the body portion and sleeve 16 on the plate clamping members.

The rear ends of the plate clamping members terminate as shown in Figs. 1 and 3. It will be seen that the ends 17 and 18 respectively form a substantially V-shaped pocket. A .handle19 is pivoted tothe body Vportion 5 by means of a pin 20 and carries a cam meinber 21 which is adapted to be received in the `V-shaped pocket formal between the exten- Operativel position upon upward vertical y movement of said handle, themore pressure sions 17 and 18..

A spring member or other resilient means y22 is provided to normally urge the ends 17 Iandl8 toward each other, and as the arms are pivoted between their ends the'glass engaging portions of the arms will be normally held apart. y

In. use the handling device is positioned so that the small end of the V-shaped recess formed between the ends of the arms will be uppermost as shown in Fig. .3. It is preferred that two suchl devices be used, one on v each vertical side of the sheet to be handled. On large sheets two workmen may be required to handle a. sheet, and in this case each workman can use one hand to grasp the handle 19 while the workman with his free hand can steady'thesheet. l Y

To lift'a sheet of glass the device is placed substantially as shown in the drawings, wherein the edge of the sheet is received in the groove formed in the body portion. The handle 19 is then lifted vertically, whereby the cam 21 will separate the ends ofthe arms contacting therewith, 'which will cause the sheet to be rinly clamped between lthecovered plates 10. With this construction any thickness and weight vof sheetfmay be handled without the necessity of making adjustments or the like. yAs'thelhandleislloweredfthe cam will leave the Vfshaped r recess, thus allowing the spring L22 Ato causelafseparation of the clamping plates andthusreleasing the sheet of glass.

It is to beiunderstood that the form Vof the invention 'herewithshown and described is to bet'aken asthepreferred embodiment of the same, arid that yvarious changes in the shape,.`size and arrangement of parts may be resorted'to'wi'thout depart-ing from the spirit oftheinvention or the scope of thesubjoined claims. f
